FINS - ARBS

FINS: Capacity Enhancement
a. Louvered Fins
Louvered fins increase the heat-transfer
capacity by creating air turbulence
which reduces the boundary layer on
the fin’s surface, but at a cost of increased
air-pressure drop across the coil.
Patterns selection
Louvered option is available for Lordan
b. Lord-Phill

LORD PHILL
This illustration
shows how the
coating reduces
surface tension.
This flattens the
water droplets
and allows a
better air flow.
Special Hydrophilic coating
Hydrophilic coating is a 2-micron
special pre-coated polymer, the
surface-tensile qualities of which cause
significant thickness reduction of the
condensing water layer. By doing so
it reduces the restriction to the airflow
(an important characteristic for
evaporators with tangential blowers).
It also prevents the phenomenon of
water carry-over from drops getting
into the evaporator’s airflow at high air
speeds.
UNCOATED
This illustration
shows an
uncoated fin,
with large round
droplets which
can restrict
airflow and
creates water
spraying.
